Therefore the maximum current in the circuit is 7.11A.

A series RL circuit includes a resistor and an inductor. The behavior of an RL circuit when a switch is closed can be determined by applying Kirchhoff's voltage law (KVL).

The voltage drops across the resistor and inductor must add up to the voltage source. The maximum current in the circuit can be calculated using Ohm's law and Kirchhoff's voltage law.

Kirchhoff's voltage law can be expressed as follows:

VL = VR + VL

Where VL is the voltage drop across the inductor, VR is the voltage drop across the resistor, and V is the voltage source.

Since the circuit is purely resistive and inductive, the voltage across the inductor and resistor can be calculated as follows:

VR = IRRL where IR is the current flowing through the resistor, and RL is the resistor's resistance.

VL = XL/dt where XL is the inductor's inductance and dt is the time difference between t = 0 and t = 0.3s.

When the switch is first closed, the current through the inductor is zero. At t = 0, the current starts to increase in the inductor until it reaches its maximum value at time t = infinity.

The maximum current in the circuit is found by calculating the steady-state current.

The steady-state current, IS can be calculated as follows:

IS = V/RL

where V is the voltage source.

The voltage source is given as 19.9V.

The resistance of the circuit, RL is given as 2.8 ohms.

Therefore,

IS = V/RL

= 19.9/2.8

= 7.11A

The maximum current in the circuit is 7.11A.

B) energy. An important underlying feature of hydraulic devices is the conservation of energy.

This is achieved through the transfer of energy from one point to another using a pressurized fluid, usually oil or water. The fluid is used to transmit force, and the conservation of energy ensures that the force applied at one end of the system is transferred to the other end without any loss of energy. This makes hydraulic devices highly efficient and effective for a wide range of applications, from construction machinery to aerospace engineering. Liquid fluid power is used by hydraulic machines to do operations. Heavy-duty construction vehicles are a typical illustration. Hydraulic fluid is pumped to numerous hydraulic motors and hydraulic cylinders located all around the machine in this type of machine and is pressurised in accordance with the resistance present.

This statement is false that If you were trying to get out of the way of a storm, you would need to know the speed at which it was moving.

If you were trying to get out of the way of a storm, you would need to know the velocity at which it was moving because,

However the mathematical formula doesn't make any difference,

\(S=\frac{d}{t}\) or \(V=\frac{d}{t}\)

d= This is the distance the storm going to cover.

t= The time within the storm going to cover the distance.

S and V is the speed and velocity of the storm respectively.

Seeing the mathematical formula we cannot make difference. But from the definition we can surely conclude that If you were trying to get out of the way of a storm, you would need to know the velocity at which it was moving. Because to get out of the way of the storm not only we have to know the path but also we have to know the storm's direction of movement.

A toy car that is 0.12 m long is used to model the actions of an actual car that is 6 m long. So, The acceleration of the actual car is 1515.15 m/s².

The solution to this question can be achieved through the use of the equation: F = ma Where F is force, m is mass, and a is acceleration.

Step 1: Calculating the mass of the toy car using the ratio of lengths m1/m2 = l1/l2, where m1 and m2 are the masses of the toy car and actual car, and l1 and l2 are their respective lengths.

Rearranging, we have:m1 = (l1/l2)m2 = (0.12 m)/(6 m) m2 = 0.02 m2

The acceleration of the motorcycle is significantly faster than that of the bicycle.While the motorcycle is able to accelerate from 90 km/hkm/h to 105 km/hkm/h in a matter of seconds, the bicycle would take much longer to go from rest to 20 km/hkm/h.

The acceleration of the motorcycle is much greater than the acceleration of the bicycle. This is because the motorcycle is able to cover a greater distance in the same amount of time due to its powerful engine and larger size.

To compare the acceleration of a motorcycle that accelerates from 90 km/h to 105 km/h with the acceleration of a bicycle that accelerates from rest to 20 km/h in the same time, follow these steps:

1. Determine the change in velocity for both the motorcycle and the bicycle.
Motorcycle: Final velocity (Vf) = 105 km/h, Initial velocity (Vi) = 90 km/h
Bicycle: Final velocity (Vf) = 20 km/h, Initial velocity (Vi) = 0 km/h

2. Calculate the change in velocity for both vehicles.
Motorcycle: ΔV = Vf - Vi = 105 km/h - 90 km/h = 15 km/h
Bicycle: ΔV = Vf - Vi = 20 km/h - 0 km/h = 20 km/h

3. Since both vehicles accelerate for the same amount of time, we can denote the time as 't'.

4. Calculate the acceleration for both vehicles using the formula: Acceleration (a) = ΔV / t

Motorcycle: a_motorcycle = (15 km/h) / t
Bicycle: a_bicycle = (20 km/h) / t

The acceleration of a motorcycle that accelerates from 90 km/h to 105 km/h is represented by the equation a_motorcycle = (15 km/h) / t. In contrast, the acceleration of a bicycle that accelerates from rest to 20 km/h in the same time is represented by the equation a_bicycle = (20 km/h) / t. To compare their accelerations directly, you would need to know the value of 't'.

Answer:

the hot air balloon

Explanation:

Warmer air is less dense than cooler air, so it rises faster compared to a cooler hot air ballon.

The balloon filled with hot air will rise higher because of its lesser density.

Density of an object is defined as the mass per unit volume of the object. It is considered as the measure of amount of substance in a give space.

Here,

Two hot-air balloons are filled at the same time. Among them, one is filled with warm air and the other one is filled with hot air.

When the balloons are released to go up, the balloon filled with hot air will rise higher. This is because of the difference in their density.

When the hot air is filled, its temperature is increased. Therefore the volume also increases which will result in the decreased density of the hot air balloon.

The balloon filled with hot air will be less denser when compared to the other. The buoyancy of the balloons is affected by their densities.

The hot air in the balloon is less denser than the cool air. So, the buoyancy of the hot air balloon will be more than that with warm air. As a result, the balloon filled with hot air will rise higher in the air.

Hence,

The balloon filled with hot air will rise higher because of its lesser density.

The alternating electric current at a wall outlet is most commonly produced by in power stations

b. a rotating coil that is immersed in a magnetic field.

An alternating current (AC) is an electrical current that periodically changes direction. In other words, the flow of electric charge in an AC circuit reverses direction at regular intervals, typically 50 or 60 times per second, depending on the frequency of the AC power supply.

AC is used to deliver electrical power to homes, businesses, and other buildings, as well as for a wide range of electrical devices and appliances, from lights and TVs to motors and refrigerators. The AC power supply is typically generated by rotating a coil of wire inside a magnetic field, which induces an alternating current in the wire.

The position of the particle at time t=6 is (37/6, 101/6).

To find the position of the particle at time t=6, we need to integrate the given velocity vector from t=1 to t=6. Integrating the x-component of the velocity vector, we get x(t) = t - 1/t + C1, where C1 is the constant of integration. Using the initial position, we can find C1 = 5.

Integrating the y-component of the velocity vector, we get y(t) = 2t + 1/t + C2, where C2 is the constant of integration. Using the initial position, we can find C2 = 4. Substituting t=6 into the expressions for x(t) and y(t), we get x(6) = 37/6 and y(6) = 101/6. Therefore, the position of the particle at time t=6 is (37/6, 101/6).

The total distance is 24 m.

The tiger's resultant displacement is 8 m.

Explanation:

Given that,

Width of tiger= 8 m

Tiger starts from the right side of the cage,

Paces to the left side

\(\Delta x_{1}=+8\ m\)

Then, back to the right side,

\(\Delta x_{2}=-8\ m\)

finally, back to the left

\(\Delta x_{3}=+8\ m\)

We need to calculate the total distance covered

Using formula of distance

\(d= x_{1}+x_{2}+x_{3}\)

Put the value into the formula

\(d=8+8+8\)

\(d=24\ m\)

We need to calculate the tiger's resultant displacement

Using formula of displacement

\(D=\Delta x_{1}+\Delta x_{2}+\Delta x_{3}\)

Put the value into the formula

\(D=8+(-8)+8\)

\(D=8\ m\)

Hence, The total distance is 24 m.

The tiger's resultant displacement is 8 m.

Analyze system dynamics and design compensator to achieve desired response by selecting compensator zero and canceling one pole of GHP(z).

To select a compensator zero to cancel one pole of GHP(z), we need to use the given angle condition:

Zzero - (pole(1) + Zpole(B)) = 180°

Here, Zzero represents the compensator zero, pole(1) represents the first pole of GHP(z), and Zpole(B) represents the compensator pole.

Let's proceed with the solution step by step:

1. First, we need to determine the value of Zzero. The angle condition states that Zzero = Zpole(1), which means the compensator zero is equal to the first pole of GHP(z).

2. Now, we need to find the value of Zpole(B). We can rewrite the angle condition as follows:

Zpole(B) = Zzero - pole(1) + 180°

Since we already know that Zzero = Zpole(1), we can substitute Zzero in the above equation:

Zpole(B) = Zpole(1) - pole(1) + 180°

Simplifying further:

Zpole(B) = 180°

Therefore, the value of Zpole(B) is 180°.

To summarize, we can select the compensator zero (Zzero) to cancel one pole of GHP(z) as Zpole(1), and the compensator pole (Zpole(B)) is determined to be 180° based on the given angle condition.

Answer:

Approximately \(5.56 \times 10^{-7}\; {\rm m}\) in this glass.

Explanation:

The frequency of a wave is the number of periods that this wave completes per unit time.

The speed of a wave is the distance that this wave travels in unit time.

Thus, dividing the speed \(v\) of the wave by the frequency \(f\) of this wave would give the distance that this wave covers in each period (cycle) of this wave. By definition, the distance that a wave covers in each period is precisely the wavelength of this wave. Therefore, an equation for the wavelength \(\lambda\) of a wave would be:

\(\begin{aligned}\text{wavelength} &= \frac{\text{speed}}{\text{frequency}}\end{aligned}\).

\(\begin{aligned}\lambda &= \frac{v}{f}\end{aligned}\).

Note that \(1\; {\rm Hz} = 1\; {\rm s^{-1}}\).

The wavelength of this light in this glass would be:

\(\begin{aligned}\lambda &= \frac{v}{f} \\ &= \frac{2.0 \times 10^{8}\; {\rm m\cdot s^{-1}}}{3.6 \times 10^{14}\; {\rm s^{-1}}} \\ &\approx 5.56 \times 10^{-7}\; {\rm m}\end{aligned}\).

The list of power sources from the lowest net energy to the highest net energy can be ordered as follows: a) PV (photovoltaic) cells, b) nuclear, and c) hydroelectric.

a) PV cells, also known as solar panels, convert sunlight directly into electricity. Although they are a renewable and environmentally friendly energy source, their net energy is relatively low compared to other sources. The efficiency of PV cells varies, but on average, it is around 15-20%. Their output depends on factors such as sunlight intensity, location, and the angle of installation.

b) Nuclear power comes from the process of nuclear fission, in which atoms of uranium are split to release a large amount of energy. Nuclear power plants are capable of producing a significant amount of electricity. However, the net energy of nuclear power is limited by the high costs of constructing and maintaining nuclear plants, as well as the management and disposal of radioactive waste. Despite these limitations, nuclear power has a higher net energy than PV cells.

c) Hydroelectric power is generated by harnessing the kinetic energy of flowing water to produce electricity. This method of energy production has the highest net energy among the three sources listed. Hydroelectric plants have high efficiency rates, typically around 90%, and are able to produce electricity consistently. Moreover, they have lower greenhouse gas emissions and a longer life span compared to other power sources. The major constraint for hydroelectric power is the availability of suitable locations with ample water resources, such as rivers and dams.
